The Solaris group is a forum where peers share technical expertise, solve problems, and discuss issues related to the Solaris operating system, including OS-related malfunctions, security issues, and network performance.

Here are the steps that I use:
1.. insert the usb drive
2.. run volcheck
3.. cd /vol/rdsk and check if the drive is there.
4.. if this is a new drive, it has to be formatted to ufs so Solaris can access it newfs /vol/rdsk/"device name". Note: any data on this drive will be deleted at this point.
5.. mkdir /usb_drive to create a mount point.
6.. mount /vol/dsk/"device name" /usb_drive.
